A person of interest has been detained in connection with a series of "random" shootings that left three people dead, including two women waiting to go to church, within an hour in the San Fernando Valley on Sunday, police said.

The person was taken into custody after an hours-long standoff with a SWAT team at a home on Polk Street near Gladstone Avenue in Sylmar on Sunday night, said Cpt. William Hayes of the Los Angeles Police Department. The person's name was not released and Hayes did not say whether guns were found inside the home.

Officials said a vehicle found at the home matches the description of the SUV sought in the shootings.

A man and two women were killed and four other people were wounded in shootings that happened in a span of 55 minutes and within a 5-mile radius in the San Fernando Valley early Sunday.

The first shooting happened at 5:50 a.m. when a 20-year-old woman was fatally shot in the 1400 block of Celis Street in San Fernando, Los Angeles Police Department Sgt. Frank Preciado said. The woman was with her parents and twin siblings on their way to early morning mass when someone came up and shot at them.

All five members of the family were struck by gunfire. Police said the twins were injured and the mother and father were in critical condition following the shooting.
